Grading apparatus

Abstract

A spreading and grading apparatus comprised preferably of a multiplicity of elongated and inverted rigid channel or u-shaped members substantially in a planar and parallel orientation attached to a supporting structure to maintain the orientation of the members and provide a preferable attachment surface for connection to a device to push or pull the apparatus.

1 . An apparatus for surface preparation comprising: 
 a. a support frame;    b. an apparatus to connect said support frame to a power source;    c. a plurality of inverted u-shaped grading members further comprising a backing portion and a first and second side portion, and a first and second edge, securedly attached to said support frame;    
   
   
       2 . The apparatus of  claim 1  wherein said apparatus to connect said support frame to a power source is a three point hitch assembly;  
   
   
       3 . The apparatus of  claim 1  wherein a grading element comprising an upper edge and a lower edge is attached to said side portion of said grading member;  
   
   
       4 . The apparatus of  claim 1  wherein a blade assembly is securedly attached to said support frame;  
   
   
       5 . The apparatus of  claim 1  wherein a scarifier assembly is securedly attached to said support frame;  
   
   
       6 . The apparatus of  claim 1  wherein said power source is a tractor;  
   
   
       7 . The apparatus of  claim 1  wherein said u-shaped grading member is a preformed metal channel;  
   
   
       8 . The apparatus of  claim 1  wherein said u-shaped grading member is two inch by five inch channel iron;  
   
   
       9 . The apparatus of  claim 1  wherein the angle of said grading member may be adjusted;
